To all whom it may concern.-

Be it known that I, ORVILLE M. Monsn, of the city of Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Improvement in Dust-Collectors, (for which patents have been granted in the following countries: England, July 20, 1886, No. 4,423; Germany, July 25, 1886, No. 39,219 France, July 27, 1886, No. 177,638; Belgium,

10 July 27, 1886, No. 74,005 Canada, September 3, 1886, No. 24,854; Italy, December 15,1887, No. 22,525, and Austria-Hungary, April 11, 1888, No. 49,960,) of which the following is a specification.

I 5 This invention relates to an improvement in that class of machines which are employed in flour-mills, factories, (be, forseparating the dust from the air which is discharged from machines in which separations are effected by air-currents-such, for instance, as middlings-purifiers, grain-cleaners, &c.

My invention relates more particularly to a dust-collector in which the dust is separated from the air by its momentum and not by straining or filtering the air through cloth; and the object of my invention is to produce il sianple and efficient dust-collector of this My invention consists of the improvements which will be hereinafter fully set forth, and

pointed out in the claims.

In the accompanying drawings, consisting of three sheets, Figure 1 is a sectional elevation of my improved dust-collector. Fig. 2

3 5 is a horizontal section in line 00 00, Fig. 1. Fig. 3 is a sectional elevation showing my improved dust-collector with an auxiliary dust-separator. Fig. 4 is ahorizontal section in line 3 y, Fig. 3. Fig. 5 is a sectional ele- 4o vation of my improved dust-collector connected with a fan.

Like letters of reference refer to like parts in theseveral figures.

A represents the stationary frame of the machine, and B the horizontal spout through which the dust-laden air enters the separator from a fan, 8.

0 represents the separating case or cham her in. which the dust is separated from the air. This chamber is made conical or taper- 5o ing in form like a funnel, and the inletspout Bis connected with the same at its large end and enters the side of the chamber C tangen: tially, as clearly represented in Fig. 2.

cl represents a small opening for the discharge of the separated dust formed in the narrow end or apex of the conical chamber 0.

E represents a cover or head which closes the large end of the chamber C, and which is provided with a large air-escape opening, 6, arranged centrally in the cover E.

frepresents 'a collar secured to the opening e and depending a short dist-anceinto the chamber C.

The dust-laden air enters the conical chamher C in a tangential direction and assumes a whirling or gyrating motion in the same, forming a vortex in which the dust particles are quickly driven to the outer side of the gyrating body of air and accumulate on the conical shell, thereby freeing the inner portion of the whirling body of air from dust. The dust particles are driven in helical lines downwardly along the inner surface of the conical chamber C toward the discharge-open- 7 5 ing d, through. which. they are finally discharged in a continuous stream. The inner portion of the whirling body of air moves in an opposite direction and escapes free from dust through the opening 6 in the head E. The area of the dust-discharge opening cl is so small compared with that of the air-escape opening that very little air escapes through the opening (Z with the dust, so that the dust can be collected withoutdifficulty by a conveyer, G, or any other suitable receptacle. I have found that with a fan having a diameter ofabout twenty inches and a width of about ten inches and running from six hundred to seven hundred revolutions per minute a conical shell having a diameter of forty inches at its base, a height of fifty-two inches, a dustescape opening one and three quarters of an inch in diameter, and an airescape opening sixteen inches in diameter will produce satisfactory results.

The depending collar f prevents any dust particles from leaving the chamber C through.

the air-escape opening (2 before they have been driven to the outer edge of the vortex.

My improved machine separates the dust from the air by its own momentum in an extremely simple manner, it employs no moving parts, is very simple in construction and operated without expense, it can be readily connected with the air-discharge spouts of middlin 's-puriiiers or other machines, and does not react upon their fans.

In the drawings the conical chamber C is arranged with its small end downwardly for the purpose of facilitating the discharge of the dust into the receptacle G; but this is immaterial, as the separation of the dust from the air does not depend upon gravitation. If desired, the axis of the cone maybe arranged horizontally, or the cone may be arranged with its small end upwardly, as may be most convenient.

In the construction of my improved dustcollector represented in Figs. 3 and 1, 11 represents an auxiliary separating-shell arranged within the large portion of the conical shell C and surrounding the ainescape opening a. The shell ll is secured to the under side of the head E and is provided with one or more longitudinal skimming openings or slots, 70, for the discharge of any light dust particles which may enter this shell with the outgoing aircurrent. The skimm in g-openin g It is provided on its inner side with an inwardly-projecting lip or flange, i, whereby the dust particles are deflected outwardly through the opening 7L into the surrounding portion of the conical chamber C. The auxiliary separator ll eX- tends downwardly beyond the lower edge of the air-inlet spout B, as clearly shown in Fig.

J represents a vertical shaft or arbor secured axially in the auxiliary separator ll and provided with cleaners K, which are rotated by the gyrating motion of the outgoing aircurrent and which come in contact with the inner surface of the separator H and detach any dust particles which may adhere thereto. These cleaners may be used when the dust delivered to the machine damp and has a tendency to adhere to the separator H. The cleaners K consist of strips of canvas, leather, or other suitable material attached to collars Z or arms which rotate on the arbor J, and are kept in. motion by the whirling air-current.

012 represents a deflecting rib or flange secured to the inner surface of the chamber 0 near the opening of the inletspout B for the purpose of deflecting the dust particles in the upper portion of the chamber C downwardly below the opening of the spout B and preventing such particles from moving past the opening of the spent 13. The deflector m is composed of a curled strip or channel having notches or openings for the escape of the air, so that the channel will relieve itself of any excessive air-pressure which might prevent the dust particles from entering the same. It is obvious that a number of inclined or spiral flanges or deflectors may be provided on the inner surface of the chamber 0 for the purpose of accelerating the movement 01"; the dust particles toward the dust-escape opening d,- but this is not ordinarily necessary. It is also obvious that these deflectors may be formed by corrugating the conical shell (1 spirally instead of forming them by ribs or flanges secured to the inner surface of the conical shell. This formation of the shell illustrated as applied to a cylindrical shell in a pending application tiled by me June 9, 1886, Serial No. 204,686.

I do not wish to claim in this application, broadly, the combination, with the herein-described dust-collector, of an auxiliary or supplementary dust-collector or separatingchamber, and reserve the right to claim said combination in another application filed by me August 20, 1886, Serial No. 211,890.

I claim as my invention- 1. A. dust-collector consisting of a chamber having an imperforate peripheral wall in which the whirling body of air forms a vortex and in which the air moves from the periphery toward the axis of the vortex as it becomes freed from the solid matter, said chamber being provided at one end with a discharge-aperture for the purified air opening into the atmosphere and at its opposite end with a discharge-opening for the separated dust and with a tangential inlet for the dust-' laden air, substantially as set forth.

2. The combination, with a dust-collector consisting of a separating chamber constructed with an imperforate peripheral wall in which the whirling body of air forms a vortex, and which is provided in one end with a discharge-aperture for the purified air opening into the atmosphere and at its opposite end with a discha'rgeopening for the separated dust, of a tangential inletspout and a fan whereby the dust-laden air-current is propelled through said spout into the dust-collector, substantially as set forth.
